Let the width = x -12
the length = x
we have this area equation: x(x-12)=380.16
=>x^2-12x-380.16=0
=>(5x-132)(5x+72)=0
=>x= 132/5 and x= -72/5 (no)
=>The width of the poster is: 132/5 -12 =72/5 inches
If you have a graphing calculator, you can simply type it into y= and it will graph it for you. But if you need coordinates, the line runs through (0,2) , (4,5) , and (-4,1)
Answer:
see the explanation
Step-by-step explanation:
we have
Solve for t
Factor -16t
----> quadratic equation in factored form
therefore
The solutions are
Step 1: Square the first term of the binomial. Step 2: Multiply the first term and last term of the binomial together and then double that quantity (in other words multiply by 2). Step 3: Square the last term of the binomial
= 36
